摘要

Zero-dimensional (0D) nanomaterials, encompassing nanoparticles, quantum dots, and nanoclusters, represent a cornerstone of nanoscience due to their exceptional quantum confinement effects and highly tunable properties derived from carrier confinement in all three spatial dimensions. This narrative review synthesizes the latest advancements in 0D nanomaterials by conducting a bibliometric analysis of the top 50 most cited and the 50 most recent articles. The analysis uncovers pivotal research trends, dominant material classes, and burgeoning application domains. Historically, carbon-based 0D materials, such as graphene quantum dots, have dominated research, but a marked shift towards metal halide perovskites and sustainable, lead-free inorganic 0D nanomaterials is evident, particularly for advanced optoelectronic applications (e.g., light-emitting diodes, photodetectors, solar cells) and high-efficiency catalytic processes (e.g., photocatalytic water splitting, CO2 reduction). Emerging areas like chiral plasmonics, biohybrid systems, and AI-driven material design further highlight the field’s dynamism. This review delineates the evolution of 0D nanomaterials, identifies current research hotspots, and forecasts future directions, serving as an essential guide for both novices and seasoned researchers in nanotechnology.
